HYDRocARBoN-BURNER Fon GQQKINGAND HEATING.

Specification forming part 4of Letters Patent No. 48,379, dated June 27, 1865.

To all whom it may concern:

i Be it known that I, H. W. DoPP, of the city of Buffalo, in lthecountyet|i3'riea-ndState of New' York, have-'invented a new and improved modeof burning vapor. from hydrocarbon liquids for heating and cooking purposes; and I do herebydeclare that the following is an exact and true description thereof, reference being had to the accompanying drawings, and to thelettcrs of reference marked thereon.

Figure I isa perspective view ofthe model, showing the mode o f supplying three burners with vapor obtained from o'ne generator. Fig. II isa center section of the generating apparatas, showing the Vsaine in connection with a frame for supporting cooking utensils. Fig.

III is u section al cut of lthe tw`o branch burners, 1

also the vapor-controlling part of the generating apparatus, and a'partial front view of the main burner which sustains'the contiu nous vaporization. 1 v

A is the generator and top of retort. y

A in Fig. II is alittle stem with a needlepoint on one e'nd and a slot on one side at right angles, which point passes in and through a small orifice, out of which the'vapor from the retort makes its exit.

a is a square block with a hole in its center, in which is secured a crank-pin. This block, be-

`ing fitted into the slot of stem A so as to admit of a forward and backward slidin g motion when the crank-pin is turned, furnishes a firm and durable bearing -for said crank-pin,and keeps the stem A' Vin position, so as to produce a right lineal motion.

A' A A in Figs. I and III show the multiplication of what is said of A` in Fig. II. Y

Az in Fig. II is a spindle or shaft runnin-g Vthrough a tube 'which is screwed into gener,-V

ator A. This spindle is provided on one end with a crank-pin, which works and turns in the A2 .A2 A2 in Fig'. I show the multiplication,

This needle-point gradu- 4ates the quantity of vapor.

A3 in Fig. II is a tube, having one end -secured into generator A, through which the spindle A2 runs.

B is the retort.

. Y C is the perforated pla-te ot' the main burner.

C' is thecomniingling-tube. G2 is a shell, to which is attached the perforated plate G and tube Cf, the whole constitut' ing the main burner.

D is a stopping-box, intended tol-secure a tight` joint and connect the retort tothe lower part ot' the generating` apparatua'thusfgiving a chance of disconnecting readily and substituting another retortV when the one in usel should Agive out, and makingjthenven'ton entirely practicable -for general use.

E is a small' reservoir, intended to contain water. The office ot this water is to collect and absorb the residue of the oil not vaporizable and to secure the oil-controlling faucetfrom l leakage.

F is a feed-tube conducting the'oil fronioilthe top of the retort, so that. the oil will be lit up to the point where effectual vaporzation is accomplished, thus securing a more perfect way of vaporiziu g allhydrocarbon liquids composed xof unequal specific gravities--such as crude petroleum-which this apparatus ils-designed to burn.

G is the hase of the water-reservoir, constructed with two faucet-screws.

g is a faucet-screw, to let on or cut olf the supplyT of oil. such a manner as to be always surrounded with water, thus ecctually guarding against leakage of oil, as oil or otherhydrocarbou liquid" cannot remain under water or any other liquid" whose specific graigity isgreater than that. ot'

the hydrocarbon liquid.

g2 is a faucet-screw, also secured to G.' This v is to draw olf the waterfrorn reservoir E when 'desirable soV to do from au excess of residuum. 1

H is a tube-secured intoreservoir E, through.l

which thewater issupplied.

I is a conical valve, having vits scat in tu'bc'.

I-I, and being secured tothe sameby meausof a screw-box and asmallspiral spring surrounding the-valve. The object of this valve is to actas a safety-valve when at any time through a mistakeot' the operator excessive pressure Thel same is extended to.

The same is secured into Gin might be produced-as, for instance, in kindling or lighting up the apparatus when the retort is full of oil and the oil-faucet shut offso as to exclude communication with the oil reservoir, and when, at the same time the vapor-faucet is not opened to allow the escape of. vapor under such circumstances, there would be without this safety-valve great danger of the retort bursting; but this safety-va1ve,be ing in communication with and subject to the pressure of the vapor thus generated, yields andpermits the water to escape, which lowers the oil in thc retort below the point of vaporization, and then is pressed back to its seat by means ofthe spiral spring. By this arrangement under no circumstances can any accident take place.

K K arc commingling and conducting tubes for branch burners.

L L are the two branch burners, which are provided with perforated plates, through which the vapor escapes before it is ignited like the main burner.

MM represent the mode ofapplying the heat for cooking purposes.

M shows the mode of carrying oif the gases which are the products of combustion. A general objection obtains against the use of the ordinary gas-stove on account of the absence of any mode ot' removing the gases obtained from the combustion, these gases being exhausted in the room where the said gas-stove is operating. To overcome this objection in this apparatus a connection can be made with M' and a chimney or other aperture'by means of a pipe or tube. This connection with chimney is not needed to create a draft, there being no need for such application in gas or vapor stoves, but is especially desirable for thev purpose described.

To operate this apparatus, a reservoir of coal-oil or other hydrocarbon liquid at an altitude of two or more feet is attached by'eonnection at G. Water is to be supplied to reservoir E by. means of tube H. Then primary heat is to..be applied to the generator A and retort B- by the use of about a table-spoonfnl of alcohol, naphtha, or other suitable material placed in a cup surrounding the retortand sitting on the perforated plate C. This is to be ignited. Oil is then to be iet into the retort by turning the faucet screw handle `markedr Oil." When the alcohol is about two-thirds consumed vaporization will be effected. Now a supply ofl vapor can be given to the main burner by partially turning the middle faucethandle marked VaporJ The vapor now escapes with a current down into the conimingling-tube C', thereby mingling with the required atmosphere necessary to produce per feet combustion. Then,-aftcr thorough mingling, the vapor passes up through the perforated plate C, and, coming in contact wlth the flame of the kindling material, is ignited. When the kindling-liquid is consumed the cup is to be removed and a larger supply of vapor admitted by increased turning ot' the said faucet-handle marked VaporJ Continuous vaporization and combustion will now be sustained.

The branch burners may be operated at any time that the main burner is burning by turning the right and left hand vapor-faucets, which `permits the vapor to pass along through the comminglng and conducting tubes K K, which becomes in its passage sufficiently mingled with the 'atmosphere and may be ignited above the perforated plates of the burners L Lwith a lighted match.

To stopv the operation of the burners the ame may be extinguished by turning oli" the supply of vapor by turning the Vapor-faucethandle marked Vapor and then shutting ot' the supply of oil by turning the faucet-handle marked OiL I claim- 1. Needle-point A', in combination with spindle .A2, perforated plate C, crank-pill, sliding block, and slot, substantially as shown and described.

2. The commingliugtube C', in combination with perforated plate O, arranged and operating substantially in the manner described.
